The cabin offers the opportunity to introduce short-term and medium-term sustainability improvements in existing aircraft fleets. In order to holistically address sustainability in the aircraft cabin, the three sustainability strategies of efficiency, consistency and sufficiency are considered in this article and addressed at both product architecture and component level. At the product architecture level, it is shown that modularization has great potential to improve sustainability along the entire product life cycle, but that there is a lack of methods for modularization strategies that contribute to the development of sustainable products. Therefore, it is shown which sustainability criteria and indicators can be addressed at the different levels of a product architecture. At the component level, there is a lack of comparisons of alternative lightweight materials and design alternatives with conventional designs and materials in terms of sustainability. Therefore, it is shown how the design of lightweight methods of construction can be combined with LCA by the example of conventional and bio-based flax sandwich structures when used in an aircraft cabin. The studies show the importance of a requirements-oriented design in terms of sustainability.enhttp://rightsstatements.org/vocab/InC/1.0/sustainabilityproduct architecturelightweight designaviationcabinTechnology::629: Other Branches::629.1: AviationConference Paper10.15480/882.13645https://www.icas.org/ICAS_ARCHIVE/ICAS2024/data/papers/ICAS2024_0511_paper.pdf10.15480/882.13645Conference Paper
